Encounter groups of monsters trapped by an ancient force, break them out to steal their Essence then use these to craft powerful items.Description on the official Path of Exile website 
The Essence league and Hardcore Essence league were past challenge leagues. The leagues started on 2 September 2016 along with the release of Atlas of Worlds expansion (version 2.4.0), and ended on 28 November 2016. There were 40 optional challenges, and players were rewarded with Essence-themed microtransactions after finishing 12, 24, and 36 challenges.
In this league, zones contained a pack of frozen monsters which held an Essence, where taking it freed the monsters imbued with its power. Essences can be used to modify items with a specified guaranteed affix, some of which are exclusive to Essences. Essences can be traded to vendors for higher tiers and can even be corrupted for a chance to gain an even stronger Essence or destroy it.
At the end of the leagues, all characters and stashes were moved to Standard league and Hardcore league. Characters that died in the Hardcore Essence league were immediately moved to the permanent Standard league.
